And it is a technological dead end.

First, the effort to make it happen is big. You have to lay fibre to
the transformation substation closest to the user. Still, the bandwith
isn't very good. And, last but not least, the wires are unshielded. So
they are acting like *huge* antennas - emitting a lot of garbage waves
and flooding big parts of the frequency spectrum. Radio traffic often
is disturbed, and, of course, you neighbours can easily listen in on
what your doing - more easily than with Wi-Fi.
